MinerU — turns PDFs and Office documents into LLM-ready Markdown and JSON for agents and RAG pipelines, Apache-2.0 plus terms
The README install route uses uv for a clean virtual environment.
Install the current major line from PyPI into that environment.
Parse a PDF to Markdown at the standard tier, or start the built-in web UI.
Tables, formulas, figures and reading order survive the conversion — not just a text dump.
Page and block locators let an agent re-read exactly the passage it cited, instead of re-parsing the whole file.
The standard tier balances accuracy and speed; the README documents other tiers and runtimes for heavier jobs.
Use it from the command line, drive a local document library from Python, or parse through the browser UI.
The README-preferred install: a Python 3.12 venv, then the 4.x line.
pip install uv
uv venv .mineru --python 3.12
source .mineru/bin/activate
uv pip install -U "mineru>=4.0,<5"The README command: parse a PDF to Markdown at the standard tier.
mineru-kit parse document.pdf -o document.md --tier standardThe built-in browser interface for parsing without the command line.
mineru-kit webuiThe OpenDataLab team, as the document-parsing front end for LLM and agent workflows.
Yes for ordinary use — Apache-2.0 plus additional terms: a separate commercial licence is only required at 100M monthly active users or $20M monthly revenue, and online services built on it must attribute MinerU.
It preserves layout, tables, formulas and reading order, and returns stable page/block locators for citations — a text dump does neither.
No — the README says so plainly: it is a document reader, not a vector database or chat-with-documents app. It feeds RAG systems; it is not one.
Install mineru 4.x with uv into a Python 3.12 environment, then run mineru-kit parse on a PDF.
